Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If magnetic markers are laid at short spacing with high position accuracy to achieve driving assist functions, then detection accuracy and driving assist performance are improved, but installation cost increases
Solution Approach 1:
The patent combines multiple boring drills into a single installation device, allowing simultaneous creation of multiple laying positions. This merging of functions reduces the total number of positioning operations needed, thereby lowering installation cost while maintaining high position accuracy through the device's built-in positioning capabilities.
Solution Approach 2:
The installation device incorporates positioning sensors and control systems that pre-determine optimal laying positions before installation. By performing preliminary positioning and calculation, the system ensures high position accuracy is achieved without requiring costly manual surveying and repeated adjustments during installation.
2Reliability
If numerous magnetic markers are installed to cover sufficient road areas, then detection reliability is improved, but installation time and cost increase
Solution Approach 1:
The installation device is divided into multiple independent boring drills, each capable of creating laying positions simultaneously. This segmentation allows the system to install numerous magnetic markers in parallel, improving installation efficiency while maintaining detection reliability through adequate coverage of road areas.
Solution Approach 2:
The device enables continuous installation operations by having multiple boring drills work simultaneously without requiring repeated positioning cycles. This continuous action increases productivity and installation speed while ensuring sufficient marker density for reliable detection across road areas.
